Surveillance video shows Roarx at a general store 4 miles from her home buying soft drinks.

Duke said her daughter was going to meet up with the man she shares an 18-month-old child with.

"They were talking about the baby, trying to set up visitation," Duke said.

Police said the video shows her heading back in the direction of home, but instead, her white Dodge Caravan was found about 40 miles away in Bullitt County abandoned and Roarx nowhere to be found.

"She don't have any business that way. I don't know why she would go that way. So, I don't think she drove that van there," said Duke.

"She has not called, not let anybody know where she's at at all. We just kind of find it a little suspicious or maybe different that she hasn't done this. I mean, a mother of four takes off, it's not very often that happens," said Detective Jeff Kelsey with the Grayson County Sheriff's Office.

Kelsey is investigating if foul play led to the woman's disappearance.

"My heart's so heavy. I just want anyone who can help to help," said Duke.

WLKY News has learned Roarx is dependent on medication for her blood pressure.

"I do know for a fact that she was carrying a black purse with her with a Louisville Cardinals symbol on it and that was her medication," said Kelsey.

Roarx is described as a petite woman about 5 feet 4 inches tall with long blonde hair. She has several tattoos, including one on her arm.

She has ties to Bullitt County and Louisville.

Detectives are hoping to soon find out the reason behind her disappearance.

"We hope for the best and prepare for the worst," said Kelsey.

Roarx was last seen wearing a green tank top and jeans.
